FASTEN ER FOR FILE-OAS ES.

smmmm forming part of Letters Patent no. 411,849, dated October 1, 1889. Application filed May a, 1339. Serial No. 309,675. on 11106191.)

To all whom, it may concern.-

Be it known that I, THEODORE J. AMBERG, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and use ful Improvement in Fasteners for File-Gases, of which the following is a specification, reference being had to the accompanying draw ings, in which- Figure 1 is a front elevation of a portion of a file-case with my improved fastener applied thereto. Fig. 2 is a front elevation of a portion of the cover of afilecase. Fig. 3 is a front elevation showing the locking-clamp secured I 5 to the front of the file-case. Fig. 4: is a vertical section at line 4. 4 of Fig. 1.

This invention relates to fasteners design ed to be applied to file-cases.

The object of my invention is to provide a novel fastener which will securely hold the cover against accidental opening, which I accomplish asillustrated in the drawings, and as hereinafter described.

That which I claim as new will be pointed out in the claims.

In the drawings, A indicates the cover of a file-case.

B indicates the front of the file-case. This front 13 may be hinged to the case or it may 0 be fixed as may be desired.

The cover A is provided with a pendent front portion that overlays the front B of the file-case when the latter is closed, and such pendent portion is provided. with an orifice or 3 5 hole a. As file-cases are usually made of pasteboard or similar material it is preferable to re-enforce the cover A around the hole a with a piece of sheet metal I).

c is a stud secured to the front B of the 40 file-case in such position that when the cover A ofzthe case is closed the stud 0 will project into or through the hole a in the cover A, as shown inlFigs. 1 and 2.

d is a locking-clamp. This locking-clamp (Z is pivotally secured to the front B of the file-ease on the stud c, the outer end of the stud c in this instance being flattened to prevent the removal of the locking-clamp cl, but the parts may be otherwise secured or fastened together. The outer or free end of the locking-clamp (Z is bent backward to form a hook, which is adapted to engage with and hold the lower front edge of the pendent part of the cover A in contact with the front 13 of the file-case when the parts are in the position 5 5 shown in Fig. 1, and to elfect this the lockingclamp swings in a plane parallel with the said front wall B of the file-case. The friction is sufiicient to prevent accidental movement of the locking-clamp cl.

In use, when the cover A. is closed the stud 0 projects into the hole a, preventing the cover from being raised until the cover A and the front B are separated far enough to withdraw the stud c from the hole a. The locking- 6 5 clamp d which is pivotally secured to the front 13 will hold the cover A against the front B, when its hooked end engages with the cover A,preventing the cover A from being separated from the front I3 sufficiently to allow the stud c to be withdrawn from the hole a. \Vhen the locking clamp d is moved to the position shown in Fig. 3 its hooked end will not engage with the cover A, and the cover A and front 13 can be separated and the 7 5 cover opened or closed, as desired. By holding the cover A and front B together by means 5f the locking-clamp (Z the accidental opening of the cover is prevented, which is liable to occur when the locking-clamp is not used on account of the warping or springing of the cover or front.

The form shown is preferred, but it will be understood that it is not essential for the 1ocking-clamp to have the stud c for its pivot, 8 5 as a separate pivot may be provided.

That I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a file-casehaving a front wall B and an opening and closing lid 0 A, of a locking-clamp plate d, pivoted to the front wall and having one end bent into a clamping-hook which receives and embraces the front edge of the lid, substantially as de scribed.

2. The combination, with the cover and front wall of a file-case, of a locking-clamp having a hooked end and pivoted to the said front wall to swing in a plane parallel thereto for causing the said hooked end to embrace the front edge of the cover and hold it against directly engages the front edge of :thecover the front Wall of the case, substantially as and holds the latter against the front of the 10' described. case and in engagement with the stud, sub- 3.
